11 Claims. (01. 242ss "I'his invention relates to a hydraulic linoleumlifter ancl particularly to a crane-type device for lifting, conveying,displaying and dispensinglinoleum.

In storing, handling and displaying of linoleum, it is necessary to havea considerable men available to lift the heavy rolls injury to thelinoleum because of breakage, chipping or other serious injury thereto.

The present invention provides a system havmeasuring the amount of andmarking or scribing means so that t may be easily cut at the desiredpoint. The linoleum lift according to the invention comprises a pair ofend. stands separated by a telescoping reach member w1th each of the endstands being provided with a hydraulic jack or lifting device and meansfor oonneoting and disconnecting the stands from the ends of the roll oflinoleum and also having rollers so that the entire device may be movedabout at will.

It is an object of this invention to provide a linoleum lifting device.

It is another object of the invention to provide a linoleum lifterhaving hydraulic jacks or provding the lifting power.

It is a further object of this invention to provide a linoleum 1ifterwhch will lift various sizes or lengths of linoleum rolls.

It is a further object of this invention to provdea linoleum lifterhaving an expanding mandrel for one end of the roll.

It is still further object of this invention to provide a linoleum lfterWhich may be moved then anchored in place.

Other objects and many of the attendant advantages of this inventionwill be apparent from the followng detailed description taken inconjunction With the accompanying drawing, in which:

Figure 4 is an enlarged longitudinal section through the expandingmandrel taken substantially on the plane indicated by the line 3-4 ofFigure 3;

Figure 5 is an enlarged cross section through the mandrel takensubstantially on the plane indicated by the line 55 of Figure 4 Figure 6is an enlarged cross section through the mandrel and taken substantiallyon the plane indicated by the line 6-6 of Figure 4;

Figure 7 is an enlarged detail of the auxiliary arm and mandrel forhandling short rolls;

Figure 8 is a cross section showing the locking screw for the auxiliaryarm and taken substan tially on the plane indicated by the line 88 ofFigure 7;

Figure 9 is an enlarged cross section through the oastor showing thelocking bail and taken 9-9 of Figure 1; Figure 10 is a meter togetherigure 11 is meter; and,

Figure 12 is a sectional elevation of the auxil iary mandrel for liftingrolls with a small core.

embodiment side elevation of the scriber and with the support therefor;an enlarged plan view of the Castor are swivelly mounted on the brackets8 and '20, respectively, so that the platforms or end stands may bemoved about as desired.

In order to look the end stands in position a braking bail 26 is mountedon the swivel bracket 28 on an axle 3 offset from the axle of the wheel28 so that the bail 26 may be pressecl into tght engagement with thewheel i'i.

Each of the the ends of the sort of standard size of linoleum or whenthey are expanded to full length, they will extencl over and grasp thelonger rolls of linoleum.

The stands 11! and 12 also each further include a hydraulic jack havinga standard or housing 42 seeured to the base 16 by any suitable meanssuch as Welding 44. The housing 42 extends in parallel relationship tothe standard 32 and the sleeve 36 is provided with a gude 46 whichembraces the housing 42 so that the sleeve 38 is non-rotatably mountedon the standard 32. In this marmer, the platforms 18 are maintained attransverse relation to the reach bar 14so that the standards 18 and 12may pass closely adjacent to the ends of rolls of linoleum or othermaterial lying on the floor.

Each of the hydraulic jacks 42 comprises in addition to the housing 42 apiston driving a piston rod 52 which has:a sheave 54 mounted at the topthereof. The piston 50 is operated by means of a pump"5 l operated by ahandle 58 on which is placed a foot bail5tl sothatthehandle 58 may beconveniently operated by the oot of the operator.

The force of the jack 42 is transmittedto the sleeve 35 by means of acable B2 having an eye 84 connecte to a hook 6'6 rigidly mounted en theside of the housing 42 and having an eye 58 connected to a hoek or eye"lil rigidly eonnected to the sleeve 35. Because of the entrainmenteiect of the cable 62 over the sheave 54, the stroke of the piston rod52 is doubled so that the stroke of the sleeve 35 is twice the stroke ofthe piston rod 52.

One of the standards, such 'as the standard 18 is provided with anexpansible mandrel '15 mounted in a bracket 16 rigidly secureol to thesleeve 86 and having a threaded oore '18 provided with reverselydireoted core threads 88 and 82. Floater bars 84 are provided withpivoted arms 85 and 88 which are respectivlyeonneeted to nuts 9o and 92.The sorew rod: '18 is maintained in the hearing block "15' by means of alocking collar8ii. The screw rod "18 is provided with a ratchet 84 Whichis driven by a ratchet wheel 98 having a driving arm 98. The wheel 9e isprovided with a pawl 1811 erossed by a spring 182 which may be reversedso that the arm 913 may be operated. in a singled-ireetion te rotate thescrew '18-ineither of itsdirections. The ioater bars 84 are preventedromrotation, operation of the handle willcause thenuts 80 and 82 teapproaeh or recede rom each other depending upon the settingo the pawl1118.

The opposite end of the stand -12 is provided. With a fixed mand-rel 110Whichis preferably a wooden roller journaled on an axle 112. The axle H2is pref-erably fixediy mounted in a braeket 114 corresponding to-thebracket 26.

In order to accommodate rolls of less length than the normal standardshort length, an auxiliary arm 116 provided with a sleeve 1 18 isslidably mounted on the telescopingmember 38 and has provided at thelower end thereofwith a braeket i251 in whicli is mounted an axle 122 onwhich is mounted an auxiliarymanclrel 124 having an outer enlarg'e'dportion 125 and an inner reduced portion 128. The sleeve 118"is providedwith an aperture 130 in which is adjusted a.setscrew 132.

A meter carrier is provided with a sleeve 1411 earrying an arm 142havingan end bracket 144 in whieh is secured an axle 1415. A standardlinear measure meter 148 hasthe opera-ting roll ti0n 1511 thereofjournaled on the shaft 145. The arm 142 also earries the bleek 152 whichhas an aperture 15e in which is mounted a screw threaded rod 155 havinga scriber point 158.

In order to make the lift adjustable to rolls having exceedingly smallinner or internal diameter, an auxiliary mandrel 1511 (Figure 12) isprovided With an internally serew threaded aperture 182 adapted to screwonto the end of the screw rod '18 so that a mandrel 0 small diameterwill be available for attaching to rolls of small internal diameter.

'Ihe operation of the linoleum lifter is as follows: Move the lifterdirectly over the roll rom whieh yardage is to be out, having the jacks32 aeein thedirection the linoleum is to be pulled out. Insert thefloater bars 84 of the expanding mandrel, into the c0re of the linoleumleaving the 'ioater bars 84 exposed approximately two inches. With theingers of one hand on one of thefloater bars 84, apply the hand: lever&&-in a cloelcwise direction until the .mandrel has expanded firmlyagainst the core of the linoleum. With the hydraulio relief valve 1'18at.the:base oi -the eylncler 565 closed, raise the linoleum to aolesired height. Now, insert the mandrel. 1111 on the opposite end ofthe lift into the-eoreof the linoleum, leaving approximately two inchesexposed. Close the relief valv.e 1111 and r=aise the linoleum to a levelheight. Theliter. may then be moved forward to transport the roll. ortomove t.to a plaoewhere it isto:be:.displayed. After so doing step tliefoot brakes 26: firmly against the castors 24.
